I am currently in the painting process of the same model. I am using the classic dark earth and dark green colors on top with duck egg blue on the underside. As Xanadu says, there are tons of pics and info on the web you can use as a start. The Guillow plan shows camo patterns, and there are many others, but what is good is you don't have to be exact. Feel free to make your own patterns also. The color schemes also vary greatly, but usually consist of a dark green and a brown or tan, sometimes a green with a gray. Undersides also varied, mostly grey or light blue. I've also seen some where one wing underside was painted black and the other pale blue. I also review on the web the plastic modellers kit builds. They show a lot of detail and paint schemes. Here is one good site:
